A broad range of means of COVID-19 medical diagnosis can be conducted to detect the confirmed cases of COVID-19 [8] . These means are contributing together to daily count up each new confirmed case using electronic health records (EHR). These means of COVID-19 medical diagnosis include clinical characteristics and radiologist's diagnosis. Clinical characteristics involves human temperature monitoring and reverse transcription polymerase chain reaction (RT-PCR) [9] . Based on the human body temperature, patients' body temperatures range within ranges of 36·5-38·8°C [11] . Accordingly, available thermal sensors or thermal images can be collected as instantaneous data to investigate the potential COVID-19 [8] . Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique that is used for testing COVID-19 using a blood sample of the case. Using real time RT-PCR test confirms the actual number of confirmed cases globally [13, 14] . Moreover, point-of-care testing, Immunoglobulin M (IgM) and detection of antibodies can be applied to detecting infected cases [6, 16] .
